Description

  This application claims the benefit of priority based on Korean Patent Application No. 10-2015-0092868 dated June 30, 2015 and Korean Patent Application No. 10-2016-0080232 dated June 27, 2016, All contents disclosed in the document of the Korean patent application are included as part of this specification.

  The present invention relates to a composite powder of soot powder and a porous polymer, and more specifically, a single step (One-step) of a dispersion in which soot powder is dispersed in a solution in which a porous polymer is dissolved. In particular, the present invention relates to a composite powder (Jade sphere) in which a porous polymer is impregnated with powder particles of candy produced by spraying, a cosmetic composition containing the same, and a method for producing the same.

  When manufacturing a composite powder in which two or more kinds of powders are combined, such as a combined body of an organic powder and an inorganic powder, after manufacturing the powder particles (A) as a base, A method of manufacturing through a process of coating with another powder particle (B) is generally used, but such a technique is not only complicated by a two-stage manufacturing process but also two or more kinds of powders. There was a problem that the characteristics of this could not be demonstrated properly. On the other hand, if a composite powder is manufactured by applying the spray drying process and the electrospray process in the pulverization method, another powder particle (B) is uniform between the powder particles (A) as a base. There is a difference that a granular powder can be produced in a single step while being dispersed and permeated in a single process.

  The spray drying technique is a method in which a dissolved substance composed of raw material powder, a solvent, a binder, and the like is sprayed by a spraying unit such as a nozzle or a rotating disk, and dried instantaneously with hot air. More specifically, spray drying increases the surface area by atomizing liquid raw materials such as solutions, emulsions, dispersions, suspensions, and slurries. This is a technique for obtaining a granular product immediately dried from a liquid raw material by direct contact with a hot air stream after enlarging the heat receiving area, and is characterized by dry powdering in a single stage.

  Therefore, fine ceramics and powdered milk have the advantages that the product is in contact with heat within a few seconds and has a relatively small effect on the physical properties of the product, and that the produced product is easy to handle. In manufacturing pharmaceuticals, foods, dyes and pigments, they are widely used to obtain granules by drying natural extracts.

  In Korean Published Patent Application No. 2002-0091797, in order to produce a ceramic powder with excellent dispersibility and filling properties for resin, a slurry containing raw material powder is sprayed to form droplets and then dried. A spray drying process for obtaining ceramic granule powder is known, and Korean Published Patent Application No. 2014-0110439 discloses a method for producing spherical boron nitride powder having a certain particle size by using a spray drying method. ing.

  On the other hand, the electro-spraying technique is a method for producing fine particles by injecting a polymer solution having a certain degree of electrical conductivity and viscosity into a capillary and then applying electrostatic force. In general, when a polymer solution is ejected through a vertically positioned nozzle, gravity and the surface tension of the polymer solution are balanced to form a hemispherical drop at the tip of the nozzle. At this time, when an electric field is applied, a charge or dipole orientation is induced on the surface of the hemispherical droplet at the interface between the air layer and the solution, and the repulsive force of such charge or dipole is opposite to the surface tension. Force is generated. Therefore, the hemispherical surface at the tip of the nozzle will increase to a conical surface called Taylor cone, and if the charge or the repulsive force of the dipoles exceeds the force that can overcome the surface tension, it will be charged. A polymer solution is released from the Taylor cone. At this time, in the case of a polymer solution having a low viscosity, it is ejected as fine droplets due to surface tension. Electrospraying also consists of a single stage of powdering, similar to spray drying.

  Electrospray has a simple device configuration and structure, is easy to manufacture, and the generated particles not only have a monodisperse distribution, but also produce particles of various sizes from tens of nano to hundreds of micro It has been widely used in fields such as thin film deposition, coating on metal surfaces, mass spectrometry of proteins and biochemicals, and structural interpretation.

  Recently, research to apply to the production of particles containing drugs in the field of drug delivery has been advanced, and Korean Registered Patent No. 10-1471280 discloses a poorly soluble substance in order to improve the absorption rate of a poorly soluble drug in the body. There is known a method for producing nano-powder of an ultrafine particle poorly soluble substance by electrospraying a hardly soluble substance solution produced by dispersing a surfactant in an organic solvent and then dispersing the surfactant.

  The inventors pay attention to the fact that the above spray drying and electrospray techniques can granulate a liquid raw material in a single step, not only easily adjust the particle size of the granules, but also produce spherical particles. The present invention has come to the present invention, which is a technique for uniformly impregnating a porous polymer with amorphous rough soot powder particles using spray drying and electrospraying processes.

Korean Registered Patent No. 10-1015386 “Spray Dryer”

  The powder particles of candy are known to be contained in cosmetic compositions for the purpose of moisturizing skin and whitening skin. However, when they are formulated and applied to the skin, the surface is rough and the feeling of use is reduced. become. In addition, white turbidity occurs due to the solidification of the powder particles of the cocoon, and when makeup cosmetics are included, there is a problem that the whiteness decreases due to the turbid saturation of the cocoon itself.

  The present invention relates to a composite powder of soot powder and a porous polymer, and more specifically, after the soot powder is dispersed in a solution in which the porous polymer is dissolved, spray drying or electrospraying is performed. (Electro-Spraying) A composite powder (hereinafter referred to as soot impregnated powder) in which soot powder particles are uniformly impregnated into a porous polymer by spraying the dispersion in a single step (One-step) Body, Jade sphere), a cosmetic composition containing the same, and a method for producing the same. The meaning of “impregnation” in the present invention means a state in which other powder particles are uniformly dispersed and infiltrated between the inside of the base powder particles, so that the surface of the conventional powder particles is separated from another. It is different from a form in which powder particles are coated or supported between pores on the powder surface. The present invention will be described in detail below.

Jade
In general, jade is classified into jadeite jade and nephrite jade, but softball is different from the composition of sodium (Na) and aluminum (Al) in hardball, and is beneficial to the human body. The main component is a mineral, that is, calcium (Ca), iron (Fe), and magnesium (Mg). Therefore, the koji powder that can be applied to the present invention is not limited to the kind thereof, but soft balls are more preferably used.

  The Chuncheon jade used in the present invention is a high quality Nephrite Jade produced in the Chuncheon area of Gangwon-do as a kind of soft jade. ) Is a mineral that has a fine and fine structure and a strong tough wool structure.

  The wrinkles in the present invention are those that are polished and processed into powder, and are ordinary methods implemented by those skilled in the art, and there is no limitation on the method for pulverizing soft beads. However, in this invention, it is desirable to process so that the particle size distribution of the powder particle | grains of the candy which can be used as a cosmetic composition will be 10000-20000 mesh. If it exceeds 20000 mesh, the powder effect of the wrinkles will be insignificant, and if it is less than 10,000 mesh, the surface of the impregnated powder of spherical wrinkles will become rough, and the feeling of use will be reduced when applied to the skin.

Porous polymer
In the present invention, the porous polymer impregnated with the soot powder particles is in the form of a sphere powder having oil absorption and sebum adsorption, such as polymethyl methacrylate [PMMA: poly (methyl methacrylate). In addition, polyvinylpyrrolidone [PVP: poly (vinyl pyrrolidone)], polycaprolactone [PCL: poly (caprolactone)] and poly-L-lactic acid [PLLA: Poly (L-Lactic Acid)] Of course, it can be selected from a group and is not limited thereto.

  Since such a porous polymer has a spherical particle shape, it can be easily blended in the production of various cosmetic dosage forms, and is applied to the skin by rolling the spherical fine particles on the skin. Basic cosmetics and skin for regular sebum control due to the excellent anti-painting feeling and the effect of preventing the skin from taking advantage of the light scattering characteristic of the spherical surface and the effect of improving makeup persistence. Often used in makeup products to correct tones.

Soot impregnated powder In the soot impregnated powder of the present invention, that is, in the composite powder in which the soot powder particles are uniformly impregnated into the porous polymer, the soot powder content is based on the total weight of the soot impregnated powder. It may be impregnated at 10 to 90% by weight, more preferably 50 to 90% by weight. The average particle size of the soot impregnated powder may be 5 to 20 μm. Such a feature is appropriate for application as a cosmetic in terms of the effect of wrinkle powder and the feeling of use when applied to the skin.

  In the present invention, a porous polymer dispersion obtained by dispersing a powder of soot in a porous polymer solution is spray-dried (Spray Drying) or electro-sprayed (Electro-Spraying), and the soot is formed in a single step (One-step). The impregnation powder is produced, and the soot powder can be uniformly impregnated inside the porous polymer. At this time, it is desirable to eliminate the emulsifier in order to achieve super water repellency of the porous polymer. Conventionally, the use of emulsifiers is unavoidable for porous powders produced by methods such as emulsion polymerization, but since the subsequent removal of the emulsifiers is impossible, there is irritation to the skin and the oil content of the skin. Not only does it absorb moisture, it also has the problem of dry skin. However, according to the present invention, there is no skin irritation caused by the emulsifier, and super water repellency can be realized, and only the oil can be selectively absorbed to enhance the makeup sustainability.

  The porous polymer solution is prepared by dissolving polymethyl methacrylate (PMMA) in a mixed solvent of dichloromethane (DCM) and hexanol (Hexanol), and the mixing ratio (weight ratio) of dichloromethane (DCM) and hexanol (Hexanol) is 9 : 1 to 7: 3 can be selected. Since hexanol serves to form a porous polymer pore, if the proportion of hexanol is less than 10% by weight of the total solvent, the pore size is too small, and if it is 30% by weight or more, The pore size is too large to fit.

The impregnated powder of soot according to the present invention can control the pore characteristics depending on the production process conditions. Pore characteristics that can be controlled include average pore size, porosity, and area of all pores. Specifically, the average pore size may be 15 to 800 nm, more preferably 250 to 600 nm, and the porosity may be 40 to 85%, more preferably 50 to 75%. Moreover, the area of all the pores is 1-100 m < ² > / g, More preferably, it is 5-80 m < ² > / g.

The soot impregnated powder having such characteristics can increase the oil absorption depending on the pore size and porosity. The amount of oil absorption can be explained by the mercury penetration volume (Intrusion Volume) described later. The mercury penetration volume of the soot impregnated powder according to the present invention is measured in the range of 0.5 to ⁵ cm ³ / g, and this value may be regarded as an oil absorption amount with a high confidence level.

  The conventional porous polymer has a relatively large specific surface area due to a single-size meso-porous structure, but has a low average pore size and low porosity. In the case of (1), a pore channel (Pore Channel) is formed by a multi-porous (Multi-Porous, Micro + Meso + Macro) structure, which is more advantageous in absorbing oil by capillary action.

Cosmetic composition The above-described soot impregnated powder can be applied as a cosmetic composition. At this time, the above-described soot impregnated powder is 0.1 to 5.0 weight based on the total cosmetic weight. % Is desirable. If the powder content of the cocoon is too high, not only will the properties and softness inherent to cosmetic ingredients and the feeling of use when applied to the skin be reduced, but there will also be a problem that the unit price of the product will increase due to the high price of the cocoon. . On the other hand, if the content of koji powder is small, the effect of koji powder cannot be expected.

  In addition to wrinkle powder, the cosmetic composition of the present invention includes skin wrinkle improvement, skin whitening improvement, skin elasticity improvement, face sagging improvement, skin moisture retention improvement, skin gloss improvement, skin aging prevention (for example, light Skin wrinkle formation and skin hardening suppression due to aging), functional additives for improving skin such as bear improvement and skin keratin improvement, functional additives for blocking ultraviolet rays, or general cosmetic compositions An included component may be further included.

The functional additive for improving the skin may contain a component selected from the group consisting of water-soluble vitamins, fat-soluble vitamins, polymer peptides, polymer polysaccharides, sphingolipids, natural extracts, and fermentation substances. it can. In addition, as a functional additive for blocking ultraviolet rays, an inorganic powder such as titanium dioxide (TiO ₂ ), zinc oxide (ZnO), cerium oxide (CeO ₂ : Cerium oxide) is further added. Can be included. Furthermore, the component contained in a general cosmetic composition can be mix | blended with the said functional additive as needed.

  Other ingredients included are oil and fat ingredients, moisturizers, emollients, surfactants, organic and inorganic pigments, organic powders, UV absorbers, preservatives, bactericides, antioxidants, plant extracts, pH Examples of such agents include, but are not limited to, regulators, alcohols, dyes, fragrances, blood circulation promoters, cooling agents, antiperspirants, and purified water.

  A cosmetic composition containing the above-mentioned impregnated powder of skin is preferably in the form of any one of skin, skin lotion, cream, serum, emulsion, essence, powder, foundation, spray, sunscreen, mask pack and gel. Can be formulated into a mask pack, a seat pack, a sleep pack, a wash-off pack, a peel-off pack, etc., but is not specifically limited in the dosage form and can be appropriately selected and changed depending on the purpose. .

  Hereinafter, the present invention will be described in more detail with reference to examples and drawings. However, the present invention is not limited by the following examples, and it is obvious to those skilled in the art that various changes or modifications can be made within the scope of the technical idea of the present invention. is there.

  FIG. 1 is a scanning electron microscope (SEM) image of the soot powder of Comparative Example 1, and FIG. 2 is a uniform view of polymethyl methacrylate (PMMA) particles in which the soot powder is a porous polymer. It is a scanning electron microscope (SEM) image of the surface (a) and cut surface (b) of the impregnated powder of the soot of Example 1 impregnated. As shown in FIG. 1, spray powder and electrospraying method are used to uniformly impregnate polymethylmethacrylate (PMMA) particles as shown in FIG. It is possible to make it.

Another test The following items were itemized tests impregnated powder jade produced by spray-drying method.

<Experimental Example 1> Reflectance Test A 360-740 nm reflectance spectrum of an experiment object was measured using a color difference meter (ColorMate, Scinco co, Ltd., Korea). Then, ColorMaster, which is PC software, was used to measure the reflectance. The reflectance was measured to calculate the blocking rate in the corresponding area.

  As shown in FIG. 4, the soot powder of Comparative Example 1 and the soot impregnated powder of Example 1 both show high reflectance in the visible light region band (380 to 710 nm), but in particular, 380 nm. From a longer wavelength region, the soot impregnated powder of Example 1 showed a higher reflectance than the soot powder of Comparative Example 1. In particular, in the blue light region of 380 to 500 nm, since the difference in reflectance is large, the soot impregnated powder of Example 1 shows a higher blue light blocking rate than the soot powder of Comparative Example 1. I understand.

<Experimental example 2> Whiteness (Whiteness,% R) test Whiteness is a value that represents the degree of whiteness of a color in a one-dimensional manner, and is based on XYZ color difference values in the entire visible light region in the reflectance test. The whiteness index was derived using a mathematical formula such as
WI = Y + 800 (x _n −x) +1700 (y _n −y) <CIE Whiteness>
X _n = 0.3101, Y _n = 0.3162 (C / 2 °), X _n = 0.3138, Y _n = 0.3309 (C / 2 °)

  As shown in FIG. 5, the whiteness of the soot impregnated powder of Example 1 is 94%, and the whiteness of the soot powder of Comparative Example 1 is improved by 10% from the whiteness of 84%.

<Experimental Example 3> Porosity Measurement Test In order to analyze the pore characteristics of the soot impregnated powder of Example 1, mercury (Hg) penetration analysis was performed. Infiltration volume of mercury (Induction Volume), average pore size (4V / A, V: Volume, A: area) and porosity (Porosity) using Porosimeter (Autopore IV 9500, Micrometrics, London, NH, USA) Are measured and shown in [Table 4].

上記「総浸透体積」は、単位グラム当たり浸透される水銀の量、「総孔面積」は円筒状の面積で表した全ての気孔の面積、「平均孔直径」は全ての気孔サイズの平均値、「０．２０psiaにおけるバルク密度」は０．２０psiaでサンプルの気孔を含んだ実際密度を意味する。

The above "total penetration volume" is the amount of mercury permeated per gram, "total pore area" is the area of all pores expressed as a cylindrical area, and "average pore diameter" is the average value of all pore sizes “Bulk density at 0.20 psia” means the actual density at 0.20 psia including the pores of the sample.

  As a result, in the soot impregnated powder of Example 1, an average pore size of 444.2 nm and a high porosity of 64.37% could be confirmed.

<Experimental Example 4> Oil Absorption Test After measuring 1 g of the impregnated powder of Example 1 using a balance and a Petri dish, a triglyceride having physical properties similar to human sebum using a dropper (Triglyceride) The oil was dropped and the amount of oil required until the impregnated powder of Example 1 was moistened was measured. At this time, mixing is performed using a spatula so that the oil gets wet well.

  As shown in FIG. 6, the oil absorption amount of the soot impregnated powder of Example 1 was 1.7 mL / g, and the above 3. It is very similar to the total penetration volume of 1.6797 mL / g in the porosity measurement test, which is the result of demonstrating the reliability of the oil absorption measurement result and also compared to the powder of soot It can be confirmed that the oil absorption increased by a maximum of 5 times or more. This is an effect generated by maintaining a large pore size and high porosity even though the soot impregnated powder of Example 1 contains 50% by weight of soot powder.

  Hereinafter, the soot impregnated powder produced in Example 1 was formulated into an emulsion form (mask pack) according to the composition (% by weight) described in [Table 5] below, and an itemized test was conducted.

<Experimental Example 5> Usability Evaluation Test After using the comparative dosage form examples 1 and 2 and dosage form example 1 of the present invention for 30 women aged 25 to 35 years twice a day for one month. By comparing items such as adhesion, spreadability, softness, particle agglomeration, makeup sustainability, etc., the usability as a cosmetic was evaluated up to 1 to 5 points, and the results are shown in [Table 6] below. .

上記[表６]を見れば、春川玉粉末を含んだ比較剤形例２の場合は、翡翠の粉末を全然含まない比較剤形例１に比べて粒子が固まる現象が大きく、密着性、広がり性、柔らかさ及び化粧持続性の全項目に対して低い評価値を示す。一方、翡翠の含浸粉体を含んだ剤形例１では、春川玉粉末を含んだ比較剤形例２に比べて粒子の固まりが大きく減り、密着性、広がり性が改善され、柔らかさと化粧持続性が比較剤形例１と類似したり向上した水準と示された。
したがって、本発明の翡翠の含浸粉体は、球状で起因する柔らかさと、高い孔隙率による皮脂吸油で起因する化粧持続性でも優秀な結果を示す。また、翡翠の粉末を含む比較剤形例２の最大の問題点であった粒子の固まりを大きく改善して白濁現象を防止できることを確認した。

According to the above [Table 6], in the case of the comparative dosage form example 2 containing the Chuncheon ball powder, the phenomenon that the particles are solidified is larger than that of the comparative dosage form example 1 which does not contain any strawberry powder, and the adhesion and spread are large. A low evaluation value is shown for all items of sex, softness and makeup sustainability. On the other hand, in Dosage Form Example 1 containing koji impregnated powder, particle mass is greatly reduced compared to Comparative Dosage Form Example 2 containing Chuncheon Tama powder, adhesion and spreadability are improved, and softness and makeup persistence. The properties were shown to be similar or improved to those of Comparative Dosage Form Example 1.
Accordingly, the impregnated powder of the present invention shows excellent results in the softness caused by the spherical shape and the makeup sustainability caused by the sebum oil absorption due to the high porosity. In addition, it was confirmed that the cloudiness phenomenon can be prevented by greatly improving the particle mass, which was the biggest problem of Comparative Formulation Example 2 containing soot powder.

<Experimental Example 6> Reflectance Test of Dosage Form In order to measure the blocking rate in the visible light region of the dosage forms of Comparative Dosage Form Examples 1 and 2 and Dosing Form Example 1, a color difference meter (ColorMate, Scinco co, ltd , Korea), the 360-740 nm reflectance spectrum of the test object was measured. Then, ColorMaster, which is PC software, was used to measure the reflectance.

  As shown in FIG. 7, the dosage forms of Comparative Dosage Form Examples 1 and 2 and Dosage Form Example 1 all appear similar to the reflectance test results in the powder state. The larger the difference in the reflectance of Production Example 1 containing soot impregnated powder, the higher the blue light blocking rate even if the soot impregnated powder is formulated.

<Experimental Example 7> Whiteness (Whiteness,% R) Test of Dosage Form The whiteness of the dosage form is a one-dimensional value representing the degree of whiteness of the color, and is completely visible in the reflectance test of the dosage form. Based on the XYZ color difference values in the light ray region, the whiteness index was derived using the following mathematical formula.

WI = Y + 800 (x _n −x) +1700 (y _n −y) <CIE Whiteness>
X _n = 0.3101, Y _n = 0.3162 (C / 2 °), X _n = 0.3138, Y _n = 0.3309 (C / 2 °)

  As shown in FIG. 8, the whiteness of Comparative Dosage Form Example 2 and Dosage Form Example 1 containing soot powder or soot impregnated powder is significantly higher than that of Comparative Dosage Form Example 1 containing no soot powder. It was confirmed that the whiteness of the impregnated powder of the dosage form example 1 was the highest, although it was fine.
